If line b is perpendicular to line a, and line c is perpendicular to line a, what is the slope of line c?mc = _____

Answers

we know that

If line b is perpendicular to line a, and line c is perpendicular to line a,

then

line b and line c are parallel

and two lines parallel have the same slope

Find the slope of the line b

Let

$A(-3,-2)\nB(2,3)$

The formula to calculate the slope between two points is equal to

$m=((y2-y1))/((x2-x1))$

$(x1,y1)=(-3,-2)\n(x2,y2)=(2,3)$

substitute

$m=((3+2))/((2+3))$

$m=((5))/((5))$

$m=1$

therefore

the answer is

the slope of the line c is

$mc=1$

If two lines are perpendicular, then the product of the slope is -1.

Thus, the slope of line c is m which is the same as line b.

What is the linear system?

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

Line b is perpendicular to line a, and line c is perpendicular to line a.

To find

The slope of line c.

We know that the slope theorem

If two lines are perpendicular, then the product of the slope is -1.

Let the slope of line b be m, then the slope of line a will be .

$\rm m_am_b = -1$

Then

$\rm m_a = -1/m_b$

Then the slope of line c will be.

$\rm m_am_c = -1$

Then

$\rm m_c = m_b$

Thus, the slope of line c is m which is the same as line b.

Explain how to divide 3/4 ÷ 3/8 by using reciprocal of 3/8

Answers

The reciprocal of 3/8 would be 8/3 (basically reversing the numbers).

When dividing fractions, you can just multiply the first fraction by the reciprocal of the second fraction instead of dividing by the second fraction.

3/4 ÷ 3/8

= 3/4 × 8/3

Simplifying gives us the final answer:

= 2

Let me know if you need any clarifications, thanks!

What's -96= -6 (8 - k)

Answers

Divide both sides with -6 to then get 16=8-k. Then subtract 8 to both sides. to get 8=-k. Finally, divide both sides by -1 to get your answer, -8=k.

1-2-3-4-5-...-97-98-99=?

Answers

we use the sum of an arithmetic formula
1 -2 -3 - 4 -5 ....-96 - 97 - 98 - 99 = 1 + Sn

$S_(n) = ( a_(1) + a_(n) )/(2) * n$

n = 98 (-2, -3,......98, -99)
a₁ = -2
a₉₈ = -99

$S_(98) = (-2 + (-99))/(2) * 98 = (-101)/(2) * 98 = -50,5 *98 = 4949 \n \n 1 - 4949 = -4948$
